Hello; I saw a televised report some time back about how passenger planes are cleaned. As I recall the turnaround between flights may be as little as thirty minutes so some things are changed out, but little more than a quick surface cleaning is done. There may be several flights by the same airplane each day. I think there is a more general cleaning about once a day during a routine service. New covers may be put on the pillows but the pillows are not cleaned or changed as I recall. The blankets were pretty much reported to only be folded and put in their place. If a plane is out of service for some mechanical repair there can be a more thorough cleaning. These recollections should be checked out to see if any new procedures are now in place.
Another thing that seemed a bit unsettling to me was how the cabin air is handled. The cabin air has to be pressurized as the plane gains altitude. The way I recall it was described is that they bleed some pressurized air from the compressor turbines of the engines. The air is circulated over and over thru the cabin. I recall that the air filters are nothing special and do not filter very small stuff. Also that the pressurized air has a small amount of oil included when bleeds off the engine. Again this should also be re-checked for accuracy. According to the current guidelines the cabin air has nothing to do with transmission of Ebola.
